Updated gtk2 packages that fix one security issue and several bugs are nowavailable for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having lowsecurity impact. A Common Vulnerability Scoring System (CVSS) base score,which gives a detailed severity rating, is available from the CVE link inthe References section.

An integer overflow flaw was found in the X BitMap (XBM) image file loaderin GTK+. A remote attacker could provide a specially-crafted XBM image filethat, when opened in an application linked against GTK+ (such as Nautilus),would cause the application to crash. (CVE-2012-2370)

This update also fixes the following bugs:

* Due to a bug in the Input Method GTK+ module, the usage of the TaiwaneseBig5 (zh_TW.Big-5) locale led to the unexpected termination of certainapplications, such as the GDM greeter. The bug has been fixed, and theTaiwanese locale no longer causes applications to terminate unexpectedly.(BZ#487630)

* When a file was initially selected after the GTK+ file chooser dialog wasopened and the Location field was visible, pressing the Enter key did notopen the file. With this update, the initially selected file is openedregardless of the visibility of the Location field. (BZ#518483)

* When a file was initially selected after the GTK+ file chooser dialog wasopened and the Location field was visible, pressing the Enter key did notchange into the directory. With this update, the dialog changes into theinitially selected directory regardless of the visibility of the Locationfield. (BZ#523657)

* Previously, the GTK Print dialog did not reflect the user-defined printerpreferences stored in the ~/.cups/lpoptions file, such as those set in theDefault Printer preferences panel. Consequently, the first device in theprinter list was always set as a default printer. With this update, theunderlying source code has been enhanced to parse the option file. As aresult, the default values in the print dialog are set to those previouslyspecified by the user. (BZ#603809)

* The GTK+ file chooser did not properly handle saving of nameless files.Consequently, attempting to save a file without specifying a file namecaused GTK+ to become unresponsive. With this update, an explicit test forthis condition has been added into the underlying source code. As a result,GTK+ no longer hangs in the described scenario. (BZ#702342)

* When using certain graphics tablets, the GTK+ library incorrectlytranslated the input coordinates. Consequently, an offset occurred betweenthe position of the pen and the content drawn on the screen. This issue waslimited to the following configuration: a Wacom tablet with inputcoordinates bound to a single monitor in a dual head configuration, drawingwith a pen with the pressure sensitivity option enabled. With this update,the coordinate translation method has been changed, and the offset is nolonger present in the described configuration. (BZ#743658)

* Previously, performing drag and drop operations on tabs in applicationsusing the GtkNotebook widget could lead to releasing the same resourcetwice. Eventually, this behavior caused the applications to terminate witha segmentation fault. This bug has been fixed, and the applications usingGtkNotebook no longer terminate in the aforementioned scenario. (BZ#830901)

All users of GTK+ are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues.
